چکیده
In this paper, we introduce the notion of Gaussian processes indexed by probability density functions for extending Matérn family covariance functions. We use some tools from information geometry to improve efficiency and computational aspects Bayesian learning model. particularly show how a inference with process prior (covariance parameters estimation prediction) can be put into action on space Our framework has capacity classifiying infering data observations that lie nonlinear subspaces. Extensive experiments multiple synthetic, semi-synthetic real demonstrate effectiveness proposed methods in comparison current state-of-the-art methods.

Variational Bayesian Multinomial Probit Regression with Gaussian Process Priors
It is well known in the statistics literature that augmenting binary and polychotomous response models with gaussian latent variables enables exact Bayesian analysis viaGibbs sampling from the parameter posterior. By adopting such a data augmentation strategy, dispensing with priors over regression coefficients in favor of gaussian process (GP) priors over functions, and employing variational a...
متن کاملBayesian inference with rescaled Gaussian process priors
Abstract: We use rescaled Gaussian processes as prior models for functional parameters in nonparametric statistical models. We show how the rate of contraction of the posterior distributions depends on the scaling factor. In particular, we exhibit rescaled Gaussian process priors yielding posteriors that contract around the true parameter at optimal convergence rates. To derive our results we e...
متن کاملBayesian Regression and Classification Using Mixtures of Gaussian Processes
For a large data-set with groups of repeated measurements, a mixture model of Gaussian process priors is proposed for modelling the heterogeneity among the different replications. A hybrid Markov chain Monte Carlo (MCMC) algorithm is developed for the implementation of the model for regression and classification. The regression model and its implementation are illustrated by modelling observed ...
متن کاملBayesian Image Segmentation Using Gaussian Field Priors
The goal of segmentation is to partition an image into a finite set of regions, homogeneous in some (e.g., statistical) sense, thus being an intrinsically discrete problem. Bayesian approaches to segmentation use priors to impose spatial coherence; the discrete nature of segmentation demands priors defined on discrete-valued fields, thus leading to difficult combinatorial problems. This paper p...
متن کاملExploiting Informative Priors for Bayesian Classification and Regression Trees
A general method for defining informative priors on statistical models is presented and applied specifically to the space of classification and regression trees. A Bayesian approach to learning such models from data is taken, with the MetropolisHastings algorithm being used to approximately sample from the posterior. By only using proposal distributions closely tied to the prior, acceptance pro...
